Title: Complementary semiconductor device
Inventor: ASAI SOTOHISA
IPC: H01L27/08
Filed: 1981-09-08
Abstract: PURPOSE:To raise the integration density by suppressing latch-up through deepened junction of the diffusion layers for ohmic contact of the power source terminal to the substrate and well layer and by eliminating necessity of making large the interval between the source and drain of MIS FET formed on the substrate and well. CONSTITUTION:Latch-up can be suppressed because the base resistance R1 of lateral P-N-P transistor Tr1 and the base resistance R3 of vertical N-P-N transistor Tr2 can be reduced by deepening the junction of the N<+> diffusion layer 32 and P<+> diffusion layer 21 for the ohmic contact. When R1 is reduced, the base voltage of Tr1 is more stabilized and when R3 is reduced, the base voltage of Tr2 is stabilized and thereby generation of positive feedback loop can be suppressed. When any one of the base resistances R1 and R2 is reduced, a resultant suppression effect can be obtained.

Abstract: PURPOSE: To obtain a letter plate having an edged letter, which permits easily controlling the light permeability of a contour portion of the letter and which has a distinct border between a letter section and non-letter section of the letter plate, by combining two sheet materials for shaded letters together.  
     CONSTITUTION: Two photosensitive sheet materials are prepared. A negative letter of a normal thickness is formed on one of these sheet materials. A letter section of this sheet material is rendered transparent, while a non-letter section, i.e. the remaining section, of the same sheet material is rendered semi-permeable. The same negative letter of a greater thickness, which is to form a contour portion of an object letter, is formed on the other sheet material. A letter section of the second sheet material is rendered transparent, and a non-letter section, i.e. the remaining section, of the same sheet material semi-permeable. When these two sheet materials are laminated, a letter plate 1, wherein that part of the lamination which consists of the semi-permeable sections of the original sheet materials becomes non-permeable and constitutes a non-letter section 4; and that part of the lamination which consists of a semi-permeable section of one sheet material and a transparent section of the other becomes semi-permeable and constitutes a contour portion 3, can be obtained.

Abstract: PURPOSE: To prevent the occurrence of the steeling of a car which is susceptible to occur while a driver is away from his car, by a method wherein, even if an ignition key is pulled off, an engine is kept in an operation state.  
     CONSTITUTION: If a key 2 is inserted into a lock 3 and is turned to a ST position, a stater for an engine activates, an the key 2 turns to a IG position. With this, if the key 2 is pressed in an insertion direction, a first rotor 8 and a second rotor 11 move leftward through a drive piece 6 against the force of a spring 18. As a result, a projection 11f of the secondary rotor 11 presses a plate spring 21, and a terminal 22 of the plate spring 21 makes contact with a terminal 24 of a contact located at an insulator 20. Thus, a coil 15 is energized, a moving piece 13 is sucked, and a projection piece 13a engages a notch 11c. When, with under said state, the key 2 is rotated to a OFF position, the first rotor 8 turns like the rotation of the key, but the second rotor 11 stays at the IG position. Then, if the key is pulled off, conventional handle locks 4 and 5 works.

Abstract: PURPOSE: To easily and quickly perform fusing work with an accurate neat section, by interrupting a high frequency current to stop having action when a fusing work part is completed, decreasing an edge point temperature lower than a cloth plasticizing temperature to make solidifying, and forming a fusion solidified layer on a fusing part. CONSTITUTION: By advance/retreat moving a press ram 4, a tip end of an edged tool 5 is pressed to a fused workpiece 7 of synthetic fiber, to allow a high frequency induction current to flow, and an edge point part is heated rapidly to a thermoplastic temperature, to perform fusing work of the workpiece 7.
